Title: Method and apparatus for installing a replacement pipe in an existing underground conduit
Inventor: STEKETEE CAMPBELL H JR
IPC: B29C48/90
Filed: 1989-09-25
Granted: 1995-05-23
Abstract: A  thin,  flexible  tubular  membrane  provides  a  heat containment tube  for  inserting  into and  inflation within an underground conduit to be repaired.   Folded rigid thermoplastic pipe is inserted into the tube while hot and flexible.  The tubular membrane is pressurized to exclude unwanted fluids from within the existing conduit.  Hot steam is injected into the tube to heat the pipe full-length externally and internally until flexible.  The pipe is then rounded and expanded against the walls of the conduit with the tube therebetween.  The rounding and expanding of the pipe is carried out progressively by moving a plug through the pipe and by injecting hot steam under pressure behind the plug.  Methods and means for heating the pipe during insertion; for repairing short sections of conduit using a comparable section of the pipe, an inflatable bladder and a heat containment tube; for interconnecting and sealing newly installed thermoplastic pipes in a main conduit and intersecting service conduit; and for relieving longitudinal stresses in the thermoplastic pipe after installation, are also disclosed.

Title: Optical fibre monitoring
Inventor: MYERS DAVID L
IPC: G01L1/24
Filed: 1989-09-27
Granted: 1992-08-18
Abstract: ABSTRACT       A clip-on device for detecting whether or not an optical fibre is carrying a light signal subjects a first portion of an optical fibre to microbending and detects any light escaping from the fibre as a result.          The device comprises an anvil having an undulating surface and a pulsed pressure pad, driven by a motor for urging an optical fibre against the undulating surface of the anvil so that a portion of the fibre is subjected to microbending of a gradually increasing extent.  A second portion of the fibre is subjected to macrobending by a light guide, which macrobending is insufficient, by itself, to cause a substantial amount of light to escape from the fibre, but serves to concentrate the light caused to leak from the fibre by microbending of the first portion of the fibre.  A control unit, operatively coupled to the photodetectors and associated with the light guides and to the pressure pad gives an output indication on receipt of a signal from the photodetector that escaping light has been detected and, on receipt of such signal, stops the motor  so that the pressure pad is stopped from further increasing the extent of microbending of the portion of the fibre.

Abstract: CELLULAR NETWORK ASSIGNMENT PROCESSOR USING RANDOMLY TRIGGERED ADAPTIVE CELL THRESHOLDS                        ABSTRACT OF THE DISCLOSURE An  information  processor  (10)  for  solving   assignment problems using  a  matrix  of individual  processing  cells.   The location of each cell within the processor (10) corresponds to the position of the costs  in the associated  constraint space of  the assignment problem, and  each cell contains  a cost register  (12) that is stored with an  associated cost value.  A noise  generator (14) associated  with each  cell  is used  to trigger  a  variable threshold (16) in each cell so that cost values may be transmitted by each cell only  when the signal from  the noise generator  (14) exceeds the  threshold.  When  triggered,  the cell  disables  all other cells along  each dimensional axes  stemming from that  cell from  contributing  to  the  current  tentative  solution.    This disabling  is  removed  at  the  beginning  of  the  next   cycle. Successive solutions to  the assignment problem  are evaluated  by adding the  cost values  in an accumulator  (24) for  cells  that represent each particular solution.  The sums are then compared to a criteria by a comparator (28).  Thresholds are then lowered by a threshold adjustment circuit  (30) for good  solutions and  raised for bad solutions.  This leads the activity of the processor  (10) toward a final stable  state which corresponds  to a near optimal solution of the assignment problem.

Abstract: A stereophonic broadcasting system incorporating companding of the difference signal in which both the usual difference signal(s) and a compressed version of te difference signal(s') are transmitted to one or more remote receivers (70). At the receiver (70) the usual difference signal(s) and the compressed difference signal(s') are combined (84) and the resulting signal then expanded (86) to obtain a noise-reduced difference signal for dematrixing (74) with the sum signal (M) to obtain the original left (L) and right (R) signals. Utilizing both difference signals increases the effective level of the received difference signal by about 6dB, whereas the noise is increased only about 3dB, for a net improvement of about 3dB in signal-to-noise ratio, and also permits compression of the difference signal according to any desired compression law and the use of the unchanged difference signal(s) as a reference signal for controlling the expansion (146) of the compressed difference signal(s') so as to cause the amplitude of the companded difference signal to equal the level of the usual difference signal(s). That is, the expander is adaptive to any compression characteristic that might be employed at the transmitter (24). Further the availability of the usual uncompressed difference signal(s) at the receiver enables the adaptive decoding of dynamic parameters of the received signal, such as frequency response and attack and recovery times, so that all of the parameters of the original signal can be restored automatically.

Abstract: The movement of a predetermined zone of a surface of a vibrating object is measured by separating a laser beam (12) having a predetermined coherence length into a probe beam (14) and a reference beam (15). The reference beam (15) is then delayed relative to the probe beam (14) by a predetermined time interval sufficient for the probe beam (14) to travel through a predetermined distance at least corresponding to the coherence length, before being combined with the probe beam (14) to form a combination beam (24). The combination beam is then subdivided into a plurality of substantially equal component beams each (25,26,27) of which is conducted along a separate path to a location spaced from the predetermined zone substantially by one-half of the distance traveled by light in the predetermined time interval between the above location and the predetermined zone. A predetermined portion of each component beam is reflected at the respective location back into the respective path, while the remainder of each component beam is directed to the predetermined zone (35) for return therefrom at least predominantly back toward the respective location and into the respective path with attendant coherent interference of the returned probe beam part with the reflected reference beam part of the same component beam. The return light beams (50) are demodulated to obtain an indication of the movement of the predetermined zone.

Abstract: The invention relates to a cellular radio network and a method for performing location updating in a cellular radio system. The cellular radio network does not employ fixed location areas, as prior cellular radio networks do, but it employs a location area configuration which is subscriber station specific and dynamically adaptive. In connection with each location updating, it is therefore possible to select an optimal location area for the subscriber station at that particular moment, the selected location area being preferably of an arbitrary size and form. It is thus possible to define the location area subscriber station specifically in such a manner that, on one hand, it is sufficiently large so that the subscriber station does not have to perform location updating frequently but, on the other hand, sufficiently small so that the paging of the subscriber station does not load the cellular radio network too much. The network and method also allow the use of completely subscriber station specific location areas.
